PIEZOELECTRIC MATERIAL, PIEZOELECTRIC ELEMENT, AND ELECTRONIC APPARATUS |
| 摘要 |
The present invention provides a piezoelectric material which has excellent insulating and piezoelectric properties and which contains no lead and potassium and also provides a piezoelectric element and a multilayered piezoelectric element each using the above piezoelectric material. The piezoelectric material is a perovskite-type metal oxide represented by the following general formula (1). (1−x){(NayBa1-z)(NbzTi1-z)O3}-xBiFeO3  (1) In the formula, 0<x≦̸0.015, 0.80≦̸y≦̸0.95, 0.85≦̸z≦̸0.95 are satisfied. The piezoelectric element includes the above piezoelectric material and a pair of electrodes each provided in contact therewith. The multilayered piezoelectric element includes piezoelectric material layers formed of the above piezoelectric material and electrodes containing at least one internal electrode so as to be alternately laminated with each other. |
